Human or anthropogenic affect on a environment included to changes to biophysical environments and to ecosystems, biodiversity, together with natural resources caused directly or indirectly by humans. Modifying the environment to fit the needs of society is causing severe effects including global warming, environmental degradation such(a) as ocean acidification, mass extinction and biodiversity loss, ecological crisis, and ecological collapse. Some human activities that form damage either directly or indirectly to the environment on a global scale increase population growth, overconsumption, overexploitation, pollution, and deforestation. Some of the problems, including global warming and biodiversity loss, draw been shown as representing catastrophic risks to the survival of the human species.

The term anthropogenic designates an issue or thing resulting from human activity. The term was number one used in the technical sense by Russian geologist Alexey Pavlov, and it was number one used in English by British ecologist Arthur Tansley in reference to human influences on climax plant communities. The atmospheric scientist Paul Crutzen gave the term "Anthropocene" in the mid-1970s. The term is sometimes used in the context of pollution produced from human activity since the start of the Agricultural Revolution but also applies loosely to all major human impacts on the environment. numerous of the actions taken by humans that contribute to a heated environment stem from the burning of fossil fuel from a brand of sources, such(a) as: electricity, cars, planes, space heating, manufacturing, or the damage of forests.

Human overshoot

Overconsumption is a situation where resource usage has outpaced the sustainable capacity of the ecosystem. It can be measured by the ] indicate that humanity's current demand is 70% higher than the regeneration rate of all of the planet's ecosystems combined. A prolonged pattern of overconsumption leads to environmental degradation and the eventual destruction of resource bases.

Humanity's overall affect on the planet is affected by numerous factors, not just the raw number of people. Their lifestyle including overall affluence and resource use and the pollution they generate including carbon footprint are equally important. In 2008, The New York Times stated that the inhabitants of the developed nations of the world consume resources like oil and metals at a rate almost 32 times greater than those of the developing world, who exist the majority of the human population.

Human civilization has caused the loss of 83% of biodiversity loss and increased Greenhouse gas emissions.

Some scholars, environmentalists and advocates have linked warning to humanity which asserted that rapid human population growth is the "primary driver late many ecological and even societal threats." According to the Global Assessment relation on Biodiversity and Ecosystem Services, released by the United Nations' Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services in 2019, human population growth is a significant component in innovative biodiversity loss. A 2021 report in Frontiers in Conservation Science proposed that population size and growth are significant factors in biodiversity loss, soil degradation and pollution.

Some scientists and environmentalists, including biomass exceeded that of any other large land dwelling animal shape that had ever existed by over 100 times.

However, attributing overpopulation as a cause of environmental issues is controversial. Demographic projections indicate that population growth is slowing and world population will peak in the 21st century, and many experts believe that global resources can meet this increased demand, suggesting a global overpopulation scenario is unlikely. Other projections have the population continuing to grow into the next century. While some studies, including the British government's 2021 Economics of Biodiversity review, posit that population growth and overconsumption are interdependent, criticsblaming overpopulation for environmental issues can unduly blame poor populations in the Global South or oversimplify more complex drivers, main some to treat overconsumption as a separate issue.
